Currently, Smuxi has only the ability to handle one identity per connection. If you want to be connected to IRC with different ident/username/nick(s) you have to create one user per identity in the core then start one frontend per identity.

It would be better if Smuxi was able to handle multiple identities natively.

A complicated solution is to be able to create more identities, and then let each server have a default identity to use. When there only is 1 the option could be hidden in the server-configuration (or link to create a new). Quick connect could then also give the option to temporarily connect with a different identity.

Or it may just be enough to just have a "Nicknames" property on every server that, if filled in, overrides the default/main nicknames+realname for that server.

Is there more to a identity than nickname and realname? (username/password already exists)

I would say overriding the nick and realname in the server property is sufficient to archive multi identity support. A new question in this matter is when and how should the currently used nick shown (when the main identity gets overridden)?
